Customized Spatial Climate Models for North America

The climate data reported for NFI ground plots are generated using spatial climate models developed for Canada and the United States by researchers at Natural Resources Canada's Canadian Forest Service, in collaboration with the Australian National University, Environment Canada, and the National Oceanic and Atmospheric Administration.
This article, which was published by the American Meteorological Society in 2011, outlines the methods used to generate those models.
